  • Patent number: 11027042
    Abstract: This disclosure provides a method of preparing a hydrocolloid adhesive that includes the steps of mixing one or more components to produce a continuous phase, heating the continuous phased to a predetermined temperature between about 135° C. to 170° C., adding a stabilizer to the continuous phase, reducing a temperature of the continuous phase to a second predetermined temperature below 99° C., adding a discontinuous phase to the continuous phase at the second predetermined temperature, and mixing the components of the discontinuous phase and the continuous phase to produce a uniform mixture. Further, the hydrocolloid adhesive includes a super absorbent material and 0.05% to 2% by weight of a peroxide.

  • Publication number: 20110150861
    Abstract: Embodiments of the invention relate to vector constructs and methods for expression of polypeptides including multimeric products such as therapeutic antibodies. Particular constructs allow for the generation of expression products from a single open reading frame (sORF). An embodiment provides an isolated or purified expression vector for generating one or more recombinant protein products comprising a single open reading frame insert; said insert comprising a signal peptide nucleic acid sequence encoding a signal peptide; a first nucleic acid sequence encoding a first polypeptide; a first intervening nucleic acid sequence encoding a first protein cleavage site, wherein said first protein cleavage site is provided by an intein segment of a Ion protease gene of Pyrococcus or a klbA gene of Pyrococcus or Methanococcus, or a modified intein segment derived therefrom; and a second nucleic acid sequence encoding a second polypeptide.
